What kind of change does this PR introduce? (Bug fix, feature, docs update, ...)

Feature

What is the current behaviour? (You can also link to an open issue here)

When changing the blueprint configuration through the API peripheralDevice subdevices can be added and removed. Currently the removal leaves the subdevice in place with a status of 'BAD' and with the message 'Uninitialized'.

What is the new behaviour (if this is a feature change)?

This change forces the subdevice to be removed in this specific case. The change is intended as a step towards allowing a Sofie instance to be completely reconfigured via API between productions.
